WALTER L. 'EINGLI G GEORGE GREENIQEE, or GENEVA, NEW YORK, ASSIGNQRS 'r'o NATIONAL WIRE WHEEL o Ks, INc., o GENEVA, NEW YORK, A ooEroKA'rIoN To all whom it may concern:

- Be it known that we, WALTER L. RING- LING, a subject of Great Britain, and GEORGE GREENLEE, citizen of the United States of America, and residents of Geneva, in the county of Ontario,'in the State of-New York, have invented new and useful Improvements in Locking Devices for Demountable Wheels,

of whichithe following, taken in connectlon with the accompanying drawings, is a full, clear, and exact description.

This inventionrelates to certain improve 'ments in demountable wheels, preferably of the wire-spoke type, involving the use of an inner hub which is journaled on the axle and an outer hub on-the wheel proper which is removably mountedon the inner hub and held in place by a suitable cap screwing upon the inner hub and engaging the outer hub.

The main object is to provide simple and efiicient means for lockingvthe cap section in its adjusted position againstaccidental backing'ofi' or unscrewlng from the inner hub section,vand at the same tlme permit.-

I ting the removal of the cap whenever it is desired to remove the wheel by the simple adjustment of the cap-holding means or detent. i

Another object is to locate this detent in such position that it will be protected against breaking or displacement by contact with external objects.

- A further. object 1s to establish such relation between the detent and spokes that one .or the other of'the spokes may beutilized as a temporary retaining means for. fric- *tionally holding the detent in its tripped position, and also to effect the automatic release of the detent by the slightestjar of the spoke with-which itmay be engaged, as for example, in casethe detent should be inadvertently left in such position when the machine'is" started, the vibration-of the spokes serving tov automatically release the same.

Other objects and uses relating to specific parts of the locking device will be brought out in the following description.

In the drawings- Figure 1 is an end view of the central portion of a demountable wheel embodying our improved locking device.

view taken in the plane of line 33, Fig. 2.

Fig. 4- is a detail sectional view of the outer end of the detent shown as frictionally engaged with one of the spokes.

In order that our invention may be clearly Patented Sept. 30, 1919. Application filed March 30,1917. Serial No. 158,584.

understood, we have shown a'portion-of an 4 axle A, upon whichis rotatably mounted an inner hub section B' adapted to receive and support an outer hub section C- the inner end of the hub section -B being enlarged to form an abutment against which the corresponding end of the outer hub section-C normally rests when the wheel is adjusted for use. The outer end of the inner hub section B-e 'is threaded externally anden-gaged by ail-internally threaded screw-cap having the periphery of the central portion provided with a series of ratchet teeth -d, the outer hub section and cap being provided with annular shoulders normally engaging with each other to hold theouter hub section in operative position upon the inner section .B to rotate therewlth.

A one-piece locking device consisting of a detent 1 is pivoted at -l to an inwardly projecting transverse wall of the outer hub section -C, as shown more clearly in Figs. 2 and 3, and is provided at its inner end with an integral portion '2- which is movable into and out of engagement with-the teeth of the cap D-- to lock and release the latter in and from its adjusted position. v v I I The other end of the detent extends through an opening -6- in the periphery of the outer end of the hub section :C- and is provided with a laterally offset por tion 3 for frictional. engagement with the inner face of one of the adjacent spokes, as -'E, for temporarily-holdingthe de tent in its tripped position when it is desired to adjust the cap -D rotatably, as in removing the same preparatory to removing the wheel proper from the inner hub section B-.

It will be observed that the pawl or detent 1 is located in substantially the same transverse or circumferential plane as the inner ends of the outer set of spokes and between the inner ends of two adjacent spokes of the'sanie set, the purpose of .theiwheel isat rest. 1
